Assigning Elements to Workset

[richard.stewart]

Hey I’m new to Dynamo and im trying to run this script to assign elements to their worksets but im coming across a warning using Element.SetParameterByName ![Warning-Element.SetParameterByName operation failed and I don’t know why?

The List.Flatten is creating “null” even though i am inputting data?

Can someone assist me please, many thanks.
